Liverpool striker Luis Suarez has spoken of two of the most controversial incidents of his career.
Suarez was speaking with Sports Illustrated.
On the biting incident with Chelsea's Branislav Ivanovic last year, Suarez said: "Firstly, it was a matter of frustration in the heat of play.
"Secondly, you react in a fraction of a second. Something that may not seem like a big thing suddenly is and you aren't conscious of your reaction or the repercussions."
But Suarez is adamant he is not a racist - despite that incident with Manchester United's Patrice Evra three years ago.
He insisted: "My conscience is clear. Firstly, I am not a racist. There are a lot of people who could testify to that.
"Secondly, there are conversations that happen on the field, where a lot gets said.
"I am at peace. Of all the video that was available, there was not one piece of evidence to prove I had said something racist."
But Suarez added: "I've had some elements on the field that weren't very good for the game. They weren't really me. Off the field I am very shy. But I realised I had to adjust my attitude on the field.
"I want to continue to play well - without the bad attitude."
